After his election, Donald Trump quickly settled a series of business disputes — but just days before his inauguration, the president-elect’s company is still waging a legal battle against a Florida shop owner over an unpaid bill.

The matter could have been settled for what amounts to pocket change for a billionaire, but the Trump Organization decided to take its chances in court.

Now Trump stands to lose hundreds of thousands of dollars. And if he wins, it could force a small businessman — one of hundreds who say they were stiffed by Trump over the years — possibly into bankruptcy.

That businessman, Juan Carlos Enriquez, owner of The Paint Spot, won the first round of the legal skirmish last summer when a judge found a lien he slapped on the Trump National Doral golf resort was valid.
